UNC System funds Appalachian research on new drug storage and delivery method

BOONE, N.C. — Thanks to research conducted by faculty at Appalachian State University and the University of North Carolina at Chapel Hill, the delivery of life-saving vaccinations and drugs to remote regions of the world could become more cost-effective, allowing these medications to reach those in need sooner. Their study aims to provide a new strategy for the storage and transport of medications and vaccines, one that eliminates the need for refrigeration.

The project’s research team consists of Dr. Brooke Christian and Dr. Gary Pielak, who received $70,865 in grant funding from the University of North Carolina System Office for their study, titled “Exploiting Tardigrade Stress Resistance to Develop Novel Therapeutic Delivery Strategies.” Christian is an assistant professor in the Department of Chemistry of Appalachian’s College of Arts and Sciences, and Pielak is the Kenan Distinguished Professor of Chemistry, Biochemistry and Biophysics and vice chair of facilities in chemistry in UNC Chapel Hill’s Department of Chemistry.

“The soaring cost of pharmaceuticals is a problem in the United States and worldwide,” Christian said. “Since many therapeutics and vaccines on the market today are protein or peptide-based, they require costly refrigeration for transport and storage.”

According to Christian, proteins are inherently delicate: Small changes in temperature, pH or water content can render them inactive.

“The use of buffers and cold temperatures protects these drugs from degradation. The cost of the ‘cold chain’ is somewhat sustainable for developed countries but is prohibitive for drug delivery in remote areas of the world,” Christian explained.

She said the aim of the team’s research is to change the paradigm of drug delivery.

“We propose to implement a novel strategy to stabilize drugs for delivery and storage that would eliminate the need for refrigeration,” Christian said. “In addition to vaccines, which are protein-based, a few prominent examples of peptide-based therapeutics that would benefit from this technology include insulin, Herceptin for breast cancer, Lupron for prostate cancer and Victoza for the treatment of Type 2 diabetes mellitus.”

The UNC System grant will provide funding for the team to test its stabilization strategy in mice in order to monitor potential toxicity and activation of the immune response, Christian said.

Student researchers involved with the project include Harrison Esterly, a senior chemistry major at Appalachian from Belews Creek, and Sophia Yang, an Appalachian senior double majoring in chemistry and exercise science major from Beijing, China.
